Four things to pay attention to when using white water

White cement is the abbreviation of white Portland cement, which is mostly used for decoration. Moreover, its manufacturing process and decorative properties are much better than ordinary cement. Therefore, it is deeply loved by owners. In the process of using white cement for decoration, it is necessary to pay attention to the following items to ensure the good color and decorative effect of white cement.

(1) When white cement is used to prepare concrete, white or colored marble, limestone, quartz sand and stone chips of various colors should be used as coarse and fine aggregates, and other impurities should not be added to avoid affecting the whiteness and color.

(2) The construction and maintenance methods of white cement are the same as ordinary Portland cement, but the bottom layer and mixing tools must be cleaned during construction, otherwise it will affect the decorative effect of white cement.

(3) When applying white cement slurry, it is necessary to ensure that the base layer is moist and timely maintain the coating. To accelerate the solidification of the coating, 1% to 2% anhydrous calcium chloride can be added to the cement slurry, or 7% of the cement mass can be added to improve the bonding strength of the cement slurry, and solve the problems of cement slurry powdering and washing off.

(4) The alkali saturated solution formed during the hardening process of white cement, after drying, precipitates white crystals such as calcium hydroxide and calcium carbonate (called white frost) on the water surface. Low temperature and humid and windless conditions can help prolong the appearance of white frost, affecting its whiteness and brightness.

The above four precautions are all factors that affect the effectiveness of white cement. The white cement manufacturer stated that only by using the correct method can the whiteness and brightness of white cement be displayed.
